Date not saving in CDT date field

In my form, I have a date field which needs to be read-only showing current date. This will work if I set the Value to today() and in saveinto parameter, I am saving the same into my cdt date field. But, its not saving and I tried to format today() into MM/dd/yyyy and converted to date using toDate(). Nothing is working.

Please advise.

Thanks,
